I have a video player which is returning seconds while playing video. Now I have startTime and endTime which are in HH:mm:ss:ss format (eg. 00:06:29:50). I want to check if the current second is in between the startTime and endTime.
I tried to convert seconds and startTime/Endtime into unix format using dayJS but it won't work. Can someone please provide me a better idea?

So I just started programming (I don't know if this is a correct word for it). I started making a website and wanted to add a date and clock. I followed a YouTube tutorial and it works but the month number is one month behind. Is there anyway to fix this problem? Also I wanted to make month number double if its number is less than 10. I wrote the JavaScript code and it messed with the month name (In this case Gegužė).
The getMonth() method returns the month in the specified date according to local time, as a zero-based value (where zero indicates the first month of the year).
const moonLanding = new Date('July 20, 69 00:20:18');
console.log(moonLanding.getMonth()); // (January gives 0)
// expected output: 6

Using date-nfs, how can I check if new Date() is between 8am and 8pm?
You don't need to use external libraries, you can simply get the current hour by new Date().getHours(), and check if it's more then 20 or less then 8.
getHours() on the date object will be an integer between 0 and 23. So you could check if it's between 8 and 20

So that I can later on create a Countdown which tells me the days Hours minutes and second left between These two Dates.
Currently I am not able to correctly subtract those two datetimes, any ideas?

Can someone please explain to me why the implementation would choose to return a zero based month?
While I understand I can just add 1 to it to make it usable in a string, I am uncertain of the zero based reasoning, ESPECIALLY since getDate starts with 1.

How to add months to a date in JavaScript?
What's the simplest way to add X numbers of months to a date object but keep the day number? My date's will always be the first of the month.
Examples:
If my start date is "04/01/2012" and i need to add 4 months to it, the result will be "08/01/2012".
If my start date is "10/01/2012" and i need to add 4 months to it, the result will be "02/01/2013".
Try something like date.setMonth(date.getMonth()+4). This will automatically catch the overflow condition and add one to the Year.
